Summary
HyperFrames is an open-source framework from HeyGen for turning HTML, CSS, media, and seekable animations into deterministic MP4 videos. It supports local CLI usage, AI agent-based workflows, and hosted rendering, with a design focus on HTML-native authoring, agent handoffs, and reproducible results. The project includes a catalog of blocks, a comparison with Remotion, and documentation to guide installation and usage.
